I tested on two systems, one clean xenial and one clean bionic, both running the current stable LXD snap with latest ArchLinux and Debian containers. On both of them, upgrading to the kernels provided by John fixed the file_lock denials and made the containers boot again.
So as far as I'm concerned, we're good to start pushing this to Ubuntu kernels.
